Plate & Frame Filter Presses
The plate and frame filter design is the standard in basic process depth filtration for clarification and pre-filtration in industries such as the pharmaceutical, chemical, cosmetic, food & beverage, and electric utility. Plate and frame filter presses provide the lowest cost of filtration per unit of fluid processed. ErtelAlsop offers application specific filter designs, in stainless steel or polypropylene, with unique features for flow rates ranging from large volumes to pilot plant and laboratory scale.
All ErtelAlsop plate and frame filters are manufactured using our superior internally ported design. Internal porting offers a number of benefits over external porting. Internal ports allow for a greater choice of filter media in a broad range of material and thickness, including pads, paper and cloth. In an internally ported filter press the filter media itself works as the gasket, eliminating concerns over gasket-product compatibility. With no need to change gaskets, you save time, money and labor. Plate and frame filters with internal ports are also inherently more sanitary since there can be no cross-contamination of O-rings from batch to batch due to product holdup.
Larger cake accumulation results in longer filtration cycles and even more importantly, the ability to achieve efficient washing of the cake to recover valuable product for further processing. Product recovery via cake washing is one of the major economic benefits of using plate and frame filter presses.
ErtelAlsop plate and frame filter units are designed to accommodate a wide range of components. These include sludge inlet frames for cake accumulation, dividing heads for multiple-step/one-pass filtration, sanitary fittings, special piping and gauges as well as pumps and motors to meet a wide range of applications. For filtration/separation processes where a sealed, vapor-tight environment is desired, our Vapor-Master® Enclosed Plate and Frame Filter Press is the answer.
